HOT Magnum 3 Pack Foam Sleeves

Each Rite-Size foam sleeve is specially designed to prolong the life of filter media by reducing the accumulation of waste and dirt particles which can prematurely clog a filter. Fine mesh foam traps and holds dirt while the sleeve's open-cell construction promotes water flow without impairing overall filter performance. Reusable after rinsing. For best results, rinse or replace monthly.
